Abstract

PURPOSE:To automate the lubrication of hydraulic working machine by a method wherein a lubricating oil pump is connected to a hydraulic system for actuators and lubricating oil is fed to the lubricating parts of hydraulically actuated parts simultaneously when one actuator is put into operation. CONSTITUTION:The actuators 10-17 to operate crawlers 1, a cab 3, a boom 5, an arm 6, a bucket 7 and a dozer 8 are connected to a hydraulic pump 23 by means of a plurality of hydraulic systems 20 respectively equipped with a switching valve 22. In addition, the lubricating oil pump 30 is connected to one of said hydraulic systems 20. When one of the actuators 10-17 is put into operation, the lubricating oil pump 30 is also simultaneously put into operation is order to lubricate a revolving supporting part A, pivoting parts B and C through a distributing system 50 comprising a supply main pipe 51 and a plurality of distributing pipes 53 with a plurality of distributing valves 52.
